Embodiment 1
[0050] see Figure 1-11 As shown, the present embodiment is a method for the cultivation of organic selenium-enriched rice and comprehensive utilization of by-products of selenium-enriched rice. The method for cultivating organic selenium-enriched rice comprises the following steps:
[0051] Step 1: When rice seedlings are raised, selenium-rich seedling substrates are used, sowing seeds are sown at a rate of 0.8 per square meter, and the thickness of the cover is 0.5;
[0052] Step 2: Before rice transplantation, apply organic selenium-enriched special fertilizer as base fertilizer, and the application rate is 20 per mu; after plowing the land, evenly spread organic selenium-enriched special fertilizer as surface fertilizer, and the application rate is 10 per mu;
[0053] Step 3: Apply organic selenium-enriched special fertilizer as topdressing fertilizer at the end of rice tillering stage before putting it on the field, and the application rate is 30 per mu;
[0054] Step 4:...
Embodiment 2
[0071] see Figure 1-11 As shown, the present embodiment is a method for the cultivation of organic selenium-enriched rice and comprehensive utilization of by-products of selenium-enriched rice. The method for cultivating organic selenium-enriched rice comprises the following steps:
[0072] Step 1: When rice seedlings are raised, selenium-rich seedling substrates are used to sow 0.9 kg of bud seeds per square meter, and the thickness of the cover is 1 cm;
[0073] Step 2: Before rice transplantation, apply organic selenium-enriched special fertilizer as base fertilizer, and the application rate is 35 kg per mu; after plowing the land, evenly spread organic selenium-enriched special fertilizer as surface fertilizer, and the application rate is 25 kg per mu;
[0074] Step 3: Apply organic selenium-enriched special fertilizer as topdressing before the paddy rice is put on the field at the end of tillering stage, and the application rate is 60 kg per mu;
[0075] Step 4: When th...
